HAND-STAMP MACHINE.

Specification of Letters Patent.

Application filed December 10, 1909.

Serial No. 532,394.

T 0 all whom it may concern:

Be it known that I, FRANK lVosmsKi, a subject of the Emperor of Germany,and resident of Brooklyn, county of Kings, State of New York, haveinvented certain new and useful Improvements in Hand-Stamp Machines, ofwhich the following is a specification.

My present invention relates to a hand stamp machine adjustable to printvarious combinations of numbers such as a series of numbersconsecutively or the same number .in repetition as well as othercombinations, and further relates to the means for rapidly adjusting themachine to print one or other of these combinations as desired.

In the drawings, which show only one of the forms which my improvementsmay take, Figure 1 is a horizontal section partly in top plan through ahand numbering machine embodying my invention, said section being takenat a point above the printing wheels; Fig. 2 is a perspective view ofthe same machine the handle portion and other non-essentials to thepresent invention be ing omitted; Figs. 3 and it are side elevationstaken from the line 3-:t in Fig. 1 looking in the direction of thearrows, por tion of the link 10 being broken away, the two viewsdiffering in that Fig. 3 shows the idle pawl in its lowered idle wheelengaging position, whereas Fig. at shows the idle pawl elevatedpreparatory to adjusting it laterally as hereinafter described Fig. 5 aface view of the idle wheel means on an enlarged scale, the leg of theprinting wheel frame and the drum that rotatably supports the idlewheels being broken off Figs. 6 to 9 inclusive are vertical sectionspartly in elevation, respectively on the lines 66 to 9-9 in Fig. 5; andFig. is a vertical section partly in elevation on the line 1010 in Fig.1 looking in the direction of the arrow.

Describing now the devices of the drawings and. reserving it to theclaims to point out the novel features and to define the scope of theinvention, 1 is the main frame of the machine consisting of a U-shapedportion 1 and a tubular portion 1 projecting from the top of theU-shapcd portion and surround ing a hole therethrough. 2 is the plungerwhich above bears the usual handle (not shown) and which below supportsthe usual U-shaped printing frame, the legs of which are shown inhorizontal section at 18 in Fig.

1, and between which the rotatable printing wheels 3 are operativelysupported in wellknown manner on an axle or drum 25. 4 is the pawl-framecarrying pawls 5 for rotating the respective printing wheels. CompareFigs. 1, 2 and 10. Said pawl-frame is provided with hinge knuckles 6which pivotally support the frame and its pawls from rod 7 securedhorizontally across between the ends of two pairs of links, one pair ona side, each pair consisting of an angular link 8 pivotally connected tothe portion 1' of the main frame at 9, and a link 10 pivotally connectedat 10 with the leg 18011 that side of the printing wheel frame. All ofthese parts of the machine are as heretofore.

Referring now more particularly to the present improvement, I haveextended the links 10 and connected them across by a shelf 11. A coiledspring 12 surrounds the rod 7 and one of its ends 12 bears againsttheunder side of the shelf, whereas its other end l2 bears against thepawl-frame a to carry its pawls 5 toward'the printing wheels so thatthey are normally in operative contact with said wheels. At one side ofthe printing wheels, a plain faced idle wheel 14 and three idle wheels15, 16 and 17 are rotatably mounted on the drum 25. Compare Figs. 1 and5. This idle wheel means will be described later in detail.

18 is the idle pawl having a hub 19 by which it is slidably supported onthe rod 7. This idle pawl has a finger 20 for engaging the periphery ofthe plain faced wheel 14, or for engaging one or other of the idlewheels 15, 16 and 17, depending on the position of adjustment into whichthe pawl is slid along the rod 7.

21 is the thumb-piece or that part of the idle pawl which is to begrasped by the operator to adjust the pawl. Said thumb piece has anopening through which is slidingly received a pin 22 that projectshorizontally from the end of the pawl-frame 4..

The shelf 11 is cut out to form the notches shown in Figs. 1 and 2opposite which are the characters C R 2 3 4. These are stamped into thematerial of the shelf for the guidance of the user in adjusting the idlepawl as will hereinafter appear.

23 is a locking fin on the idle pawl which when the pawl is in itslowered position in Fig. 3 is receivable into one or the other of thedescribed shelf notches, whereupon the pawl is locked againstaceidentallateral displacement along the rod 7. On the other hand, when the idlepawl is pivoted into the raised position shown in Fig. 1, the end of itsfin 23 clears the notched edge of the shelf and the pawl can he slidlaterally in either direction and its fin let down into any of the othernotches. Just as the spring 12 impels the pawlframe 4 toward theprinting wheels, so at the same time it impels the idle pawl toward theidle wheel means, because the pin 22 carries the idle pawl along withthe pawl frame. This same pin connection keeps the fin normally seatedin whatever notch it happens to be left in. Of course, the individualcomponents of the idle wheel means can be any desired, and thecharacters C R 2 3 4 on the shelf will vary accordingly. Hmvever, in theparticular machine shown, the significance of these characters G R 2 3 ais as follows: hen the idle pawl adjusted into notch C, its finger 20 isopposite the leg 18 of the printing wheel frame. but does not touch it.The result is that the pawls 5 are in constant engagement with theprinting wheels, and operate them at every down stroke of the plunger,thus giving consecutive numbering, symbolized by the letter (i 0.77

lVhen the idle pawl is in notch R, its finger 20 .is on the plain facedwheel 14, which is of sufficient diameter to keep all the printing pawlsoff the printing wheels, so that no matter how many times the plungermay be operated, the number printed will remain always the same. Thisrepetition of the same number is symbolized by the letter R. Next comethe other idle wheels 15, 16 and 17, respectively, engaged by the idlepawl when adjusted into notches 2, 3 and 1-. Each of these wheels hasnotches or spaces 26 alternating with unnotched or high portions. Thewheel 15 had four of these spaces 26 equidistantly disposed around thewheel, 16 has three, and 17 has two. Moreover all of the wheels havesymmetrically disposed ratchet teeth 27 on their outer face, wheels 15and 17 having eight ratchet teeth and wheel 16 having nine. These teethare positioned as follows: Thus there .is one at every space of eachwheel. The rest are located on the high places between the wheel spaces.Thus an examination of Figs. 7, 8 and 9 shows that wheel 15 has oneratchet tooth 27 on each high place, wheel 16 has two, and wheel 17 hasthree; Now depending upon whether the idle pawl is in notch 2, 3 or 4 ofthe shelf to engage idle wheel 15, 16 or 17, will cause the machine togive a series of numbers in duplicate, triplicate or quadruplicate, inother words, a series of numbers 11, 22, 33, etc.; or 111, 222, 333,etc.; or 1111, 2222, 3333, etc. Thus when the idle pawl engages one ofthe wheels 15, 16 or 17,

every down stroke of the plunger causes the pawl to push against one ofthe ratchet teeth 27 to give the wheel a partial turn. Successivedown-strokes cause the idle pawl to engage successive ratchet teeth, sothat sometimes the pawl will be riding on a high part of the wheel andsometimes will drop into the wheel spaces. It is only when the idle pawldrops into the wheel spaces that the printing wheel pawls engage andoperate the printing wheels. They are held off the printing wheels, whenthe idle pawl is riding on the high places of the idle wheels. Thereforeit follows that the idle pawl on wheel 15 gives'numbers in repeats oftwo, 1.1, 22, 33, etc. because there is one high place ratchet toothbetween spaces, which means, that following each change of number therein one idle down-stroke of the plunger which leaves the number the sameas before. Again the idle pawl on wheel 16 gives repeats of three, 111,222, 333, etc., because there are two high place ratchet teeth betweenspaces so that following each change of number there are two idledown-strokes of the plunger that leave the number the same as before.Finally wheel 17 gives re peats of four, 1111, 2222, 3333, etc., becausehaving three high-place ratchet teeth between spaces, there are threeidle plunger strokes that leave the number unchanged.

It will be understood that the plain disk 14 is in reality a plain facedidle wheel and that not only it, but also the leg 18 on the idle pawlside of the printing wheel frame are parts comprised along with the idlewheels 15, 16 and 17 under the language of the claims calling for idlewheel means having a plurality of faces arranged side by side. It willbe further understood, however, that said language is not to be taken aslimited to the particular idle wheel means shown, but to include otherdifferent forms of idle wheel means such as wheels having a differentnumber of spaces as may be desired or suitable.

In addition to the features of novelty relating to the adjustment of theidle pawl relative to the idle pawl 1neansthere is also the feature thatthe idle wheels 11 to 17 may be united to turn as one wheel, in factpreferably consist of a single casting. An ad *antage of this, .is thatonly one hub-pin 28 need be employed to engage the hubnotches (rand Z).These notches are only needed at the hub-pin and need not extend asshown across all of the wheels. However, when the wheels are a singlecasting, the lat ter is convenient from the point of view of milling.

There are eight a notches corresponding with the eight ratchet teeth ofthe wheels 15 and 17, and there are nine 5 notches corresponding withthe nine ratchet teeth of the wheel 16. This would make 17 notches inall, but in fact I get along with only 14 by combining wheel 16 with theother two Wheels so that three of the a and Z) notches come together. Inaddition, this requires doing violence to the even spacing of the bnotches which, to be accurate, should be spaced one-ninth of thecircumference apart instead. of one-eighth, which is the case where theycoincide with the a notches. However, on so small a circumference I havefound that the inaceuracyis negligible. In short, that the advantages ofthe combination, consisting in reducing the number of notches are notdiscounted by any disadvan tage or lack of perfect operation. lVhcn theidle pawl engages either wheel 15 or 17, these being the wheels with theeight ratchet teeth, it will be apparent that the notches a will beengaged in succession by the hub-pin. Further, that when the idle pawlengages wheel 16, the notches b will be engaged in succession by thehub-pin. Of course, the general purpose of the hub-pin and notches is toprevent back-lash of the idle wheels and inits broad aspect is wellknown. Finally, there is the feature consisting of means preventing sideplay of the pawl frame 4 and of its pawls out of working relation withthe printing wheels, but without interfering with the pivotal motion ofsaid frame and its pawls. For this purpose, the pawl frame 1 has avertical slot 29. 30 is a piece of sheet metal supported stationarilyfrom the shelf 11 and the rod 7 and project- .ing loosely into the slot29, whereby the pawl frame can plvot to and from the printing wheels,but cannot move laterally. The support of the piece 80 consists of therod 7 received through a hole in said. piece, and further consists ofthe shelf 11 whose edge is slotted at 11 to receive and interlock withthe piece 80 at a slot 30 similarly formed therein.
